To all whom it may concern:

Be it known that I, RICHARD S. Sranmsn, a citizen of the United States, and resident of St. Louis, and State of Missouri, have invented certain new and useful Improvements in Fireproof Boxes, of which the following is a specificatioacontaining a full, clear, and exact description, references being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in fire proof boxes and its object is to provide a box of inexpensive, and durable construction in which articles, subject to damage or destruction by heat or flame, may be safely placed and held secure against damage or destruction by heat or iiame.

My improvements consist in the novel construction, arrangement and combination of parts hereinafter fully, clearly and concisely set forth in my specification, pointed out in my claims and illustrated by the accompanying drawings, in which,-

Figure l is a view in perspective of a fire embodying my improvements, showing its door in an open position.

Fig. 2 is a view, in in which articles are placed- Fig. 3 is a longitudinal sectional elevation of the box and casing,

Fig. l is a transverse sectional elevation taken on the line H of Fig. 3, and

Fig. 5 is an end elevation of the casing.

Referring to the drawings by numerals, 6 designates the body of the casing, which is constructed oi sheet metal in the form of a rectangular open ended tube. At one end the casing is closed by a fined head 7, constructed of sheet metal, having marginal flanges 8 for securement to the casing, as best shown in Fig. 3.

Secured to the end the fined head is a hinged oi? the casing, opposite door 9, and by preference this door is provided with locking mechanism, as shown at 10.

T he door, as shown, is shaped to fit withm .the end of the casing and is constructed of two sheets of metal having therebetween a wooden insulating body ll, and for a reason hereinafter made clear the door'ismade a trifle smaller than the open end of the easto provide the spaces 12.

Fitted within the casing and in intimate contact with the inner face of the fixed head '3' is a wooden lining 13, and fitted within the specification or Letters Eetent.

casing, in intimate contact with the inner faces of the top, bottom and both sides thereof is a wooden lining 14, which extends from the lining 13 of the fixed head to a point, adjacent the open end of the casing, separated from the margins of the sheet metal casing a distance corresponding to the thickness oi the door 9 and the ends oi said lining members are beveled to fit the beveled wooden'insidelining 15 of the door.

Fitted within the casing is a number of metallic bands 16, to which are secured the spacing ribs 17, preferably constructed oi angle iron and so disposed as to furnish about along the median line of the top, bottom and both sides a slide rail or contact.

The article box or drawer 18 is constructed of sheet metal oi the same contour as the casing and provided with a hinged lid 19, and is lined throughout, including its lid, with a wooden lining 20.

This box 18 is placed within the casing and spaced from the wooden lining thereof by'thc ribs 17 and to facilitate its placement and withdrawal from the casing provide a pull 21.

Formed in the beveled faces of the lining between the door and easing there is one or more grooves 22 which, in the event the box as a whole is subjected to heat or blame, will I provide an escape for excess pressure within the box due to expansion by heat, the space between the margins of the door and the easing referred to being provided for a similar purpose. In other words, the door does not fit air tight within the casing 6. the space being only suficient to allow the escape of gases within the box but not large enough to permit the entrance oi the domes from the outside. I he grooves are likewise very small, being about one-sixteenth of an inch deep. ihe pressure being greater on the inside of the box, I found out by ezoeriment that no flames will enter the box through the spaces and grooves referred to.

Wood, as is well known, is a material possessing heat conductivity of a very low order, hence the provision of a lining lot the article drawer and the lining for the casing both constructed or" wood. The box: as a whole may be subjected to flame or heat a high temperature without danger of damage or destruction to the articles, and by placing the casing lining to engage the casing the lining will be superficially charred, without Hill being wholly consumed due to the absence of suflicient air to promote combustion to that extent, and which char further is useful as a heat insulation.

As clearly shown in Fig. 3, there is secured to the inner face of the wooden lining 13 of the fixed head 7 a spacing rib 23 and it is to be understood that the pull 21 acts as a spacer for the forward end of the box or drawer 18. It will thus be noticed that with the ribs 17 the rib 23 and the pull 21 the article box or drawer will be maintained at all times spaced throughout from the inner face of the lining of the casing, which spaces act to insulate the article box from the casing.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent is A fire proof receptacle comprising two rectangular shaped boxes, one placed within the other and the exterior surface of the inner box throughout being spaced apart from the inner surface of the outer box, each box comprising an exterior casing of relatively thin metal and a relatively thick wooden lining in direct contact with the metal whereby the application of heat to the exterior metal easlining for said closure with a mitered edge,

there being a vent opening at the juncture of the closure with the edge of the outer box suflicient to permit the escape of gases from Within and preventing the enterin from without, a hinged metallic fid for the inner box provided with a wooden lining in direct contact therewith, a handle secured to the front end of the inner box for manipulating-the same and answering as a spacing means for holding the front end of the inner box away from the closure for the outer box, and spacing ribs secured to the sides, bottom and top and one end of the outer box for holding the inner box spaced apart therefrom.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
